FAA Airplane Flifght Manual (AFM)

[cessnadriver]

Hello. My instructor is convinced that Cessna had a FAA Approved flight manual. I talked with Cessna publications about this and they said that there was no flight manual issued for that old of airplane, and REF: the AC 60-6. But since I have a copy of the original wt & bal and equipment list my instructor thinks these documents where part of the flight manual. I DON'T KNOW! Except for flying for the Civil Air Patrol which has newer airplanes, I never rented a airplane that had a FAA approved flight manual I always had the owner's manual that the flight schools sold? The specific information he is looking for is a by serial/"N" numbered flight manual?
Thanks for your reply.
